Abstract A thermodynamic analysis of a power system consisting of adiabatic compressed air energy storage and biomass gasification energy storage power system in a hybrid mode for simultaneous production of electricity and warm water for use domestically is presented in this paper. The hybrid system is designed to meet peak load power demand of 1.3 MW from a blend of 1 MW adiabatic compressed air energy storage system powered by electricity and 0.3 MW rated dual fuel (syngas + diesel) powered engine. The syngas fuel used in the dual fuel engine is supplied by a downdraft biomass gasification system whose wood feed is supplied by a hot air dryer system operated by waste thermal energy recuperated from the system. The performance of the overall system is assessed with total system efficiency, electrical efficiency, effective electrical and exergy efficiency as metrics. In addition, the performance of the sub-components of the system is appraised using exergy destruction and exergy efficiency. The overall energy and exergy efficiency of the system is found to be approximately 38% and 29%, respectively. The electrical and effective electrical efficiency, are 30 and 34%, respectively. The exergy efficiency of the sub-system components are 61.38, 21.47, 5.76, 89.17 and 86.12% for the biomass gasifier, dual fuel engine, hot air dryer, air compressor and air expander, respectively. It is found that the destroyed exergy in the components of the hybrid system is the uppermost in the biomass gasifier, then the DFE and the AE in that order. The minimum destroyed exergy occurs in the hot air dryer. The system has a primary energy savings ratio 10 which means it cannot be deployed as a CHP system under the EU criteria.

混合绝热压缩空气储能系统与生物质气化储能（A-CAES+BMGS）动力系统热力学分析

摘要 本文对由绝热压缩空气储能和生物质气化储能电力系统组成的混合模式电力系统进行热力学分析，该电力​​系统同时生产家用温水。该混合动力系统旨在满足由电力驱动的 1 MW 绝热压缩空气储能系统和 0.3 MW 额定双燃料（合成气+柴油）动力发动机混合而成的 1.3 MW 峰值负载功率需求。双燃料发动机中使用的合成气燃料由下吸式生物质气化系统供应，该系统的木材进料由热空气干燥器系统供应，该系统由系统回收的废热能运行。整个系统的性能通过总系统效率、电力效率、有效的电气和火用效率作为衡量标准。此外，系统的子组件的性能使用火用破坏和火用效率进行评估。发现系统的整体能量和火用效率分别约为 38% 和 29%。电效率和有效电效率分别为 30% 和 34%。生物质气化炉、双燃料发动机、热风干燥机、空气压缩机和空气膨胀机的子系统组件的火用效率分别为61.38、21.47、5.76、89.17和86.12%。发现混合系统组件中被破坏的火用在生物质气化器中最高，其次是 DFE 和 AE。最小的破坏火用发生在热空气干燥器中。
